• ROBERTS/PRIMERUS Poly Punch .187 Tubing

    Professionals use this punch, with its specially designed punch tip, for making holes in mainline poly tubing to insert 1/8″ poly tubing directly in without the use of a barbed coupler. After a short time the flexible poly will seal around the micro tubing creating a water-tight seal. This will also punch holes sized to insert any of the 1/4″ barbed fittings into your mainline.

    USE ON .187 X .125 TUBING
